Abstract
We experimentally demonstrate a silicon photonic carrier-assisted differential detection receiver with a single-polarization 224-Gb/s 16-QAM signal transmitted through 80-km SMF. For an integrated direct detection receiver with transmission demonstration, we achieve the highest electrical spectral efficiency/# of polarizations of 6.4 (net 4.6) b/s/Hz.
